This is the Patagonia base layer, the Women's Capilene Thermal Weight Zipneck Pullover Polartec. Color: Light blue系 Size: S (Women's) Length: Approximately 64cm Width: Approximately 43cm Shoulder width: Approximately 36cm Sleeve length: Approximately 59cm Due to the nature of the material, there is some slight pilling, but there is no noticeable damage. However, this is a USED item, so please refrain from purchasing if you are sensitive to this. The following is quoted from the web page: ■ The Capilene Thermal Weight, which is stretchy, breathable, and can be stored compactly, uses soft Polartec Power Grid material. The smooth surface allows for smooth layering, and the warm, brushed fleece on the inside quickly wicks away moisture, providing a comfortable feel against the skin. Capilene Thermal Weight contains 30-92% recycled materials and is treated with Polygiene permanent odor control, reducing the number of washes and allowing for long-term wear. It features a long front zipper to promote ventilation, a self-fabric-lined collar for comfortable skin contact, and a hang loop. The gusseted underarms allow for a full range of shoulder movement, and the offset shoulder and side seams fit smoothly under backpack straps. Elastic thumb loops cover the wrists, and the slightly longer hem in the back covers the lower back. It is finished with flatlock seams to minimize friction. Material: Polyester 92% / Polyurethane 8% Weight: 139g Production: Made in Colombia
